The most likely problem is that the DLL function being called has corrupted the memory. If you pass arrays or strings to the DLL, the DLL function cannot dynamically resize the array. Writing beyond the last element of the array or string could corrupt the memory and this may not be obvious until LabVIEW is closed."............................But it doesn't match my case. Does someone have idea about this? I Attach my .h file for reference
Which of the 2 functions do you call? How?
The documentation of InitSocketEx() seems to indicate reversed parameter order than what the function prototype looks like!
I indeed do not see much possibilities to pass in to small a buffer that the DLL function might be overwriting past the end. This really only leaves one more possibility:
Your DLL is doing something largely illegal somehow. Maybe something as silly as storing the reference to the ipAdress instead of the address itself. The memory passed as parameters into a C function is generally only valid for the duration of the call. This is especially true if you use LabVIEW since LabVIEW will re- and deallocate memory buffers frequently as soon as they are not used anymore and the parameter to a Call Library node is considered to not be required anymore after the function returns.
